## Cumulative Distribution Function of the Wakeby Distribution

### Description

This function computes the cumulative probability or nonexceedance probability of the Wakeby distribution given parameters (xi, α, β, gamma, and delta) of the distribution computed by `parwak`. The cumulative distribution function of the distribution has no explicit form.

### Usage

    cdfwak(x, wakpara)

### Arguments

`x` | A real value.
`wakpara` | The parameters from `parwak` or similar.

### Value

Nonexceedance probability (F) for x.
